1. There's enough biomass, but we'll have to have one hell of a population receed to make it work.
2. Probably. Unless they go nuts about growing algae in the desert someplace. The energy costs will make this decentralised, of course. Economically, they won't have much choice.
3. Or, we can get into hydroponic greenhouse gardening in a big way. It'd be the only viable way to farm unfarmable land.
4. Most fertilizers today are made from petroleum. Without petroleum, no fertilizers, no massive production. See my Point 1.
We having fun yet? On the upside, populations tend to fall in developed countries as the birthrate declines. There's not as much pressure to pump out a dozen kids when 11 of them will survive to adulthood. The downside to it is, it takes a lot of technology and energy to efficiently feed all those people.
